Started a bit late today, ground down all the rust with a 6″ course grind wheel on a drill. An angle grinder or some such probably would have been better as while the drill was far more maneuverable, it was shaking hell out of my hands. That matters when you are doing several hours of that crap.
I’ve also removed the radiator hoses on the loop leading to the passenger front and passenger back heaters. Didn’t like the fluids one bit, more on that in a following post.
After sweeping and using compressed air to clean out all the debris, I used a strong solution of TSP in hot water and a scrub bush to work my way across each panel, spraying and scrubbing. After that ordeal, I used remaining solution to spray over the entire floor and some spots I wanted to insure were clean. This was soon followed up with hosing out the bus with a spray nozzle several times until I was satisfied. Remaining standing water was swept out, fan was put in on high to help it all evaporate one more time.
